Referring to FIG. 9, the imaging device 200 may be fixedly arranged onthe support assembly 20 when in use.

According to mechanical analysis, if thecenter of gravity of the first support frame 10, the support assembly20, and the imaging device 200 as a whole coincides with the drivingshaft of the first driving device 42, the first support frame 10 may notgenerate a rotational torque regardless of a rotation angle of the firstsupport frame 10, i.e., the first support frame 10 may not shake backand forth due to a torque.

Therefore, the stability of the imagingdevice 200 may likewise be improved during a rotation of the thirdsupport frame 40 a.

Theadaptors 23 may be moved on the guiding posts 12 along a longitudinaldirection of the guiding posts 12 when the rotating member 722 isrotated, thereby causing the center of gravity of the first supportframe 10, the support assembly 20, the second support frame 40, and theimaging device 200 as a whole to coincide with the rotating shaft of thesecond driving device 44.
